Torque Specifications





Cylinder Head Torque And Sequence





NOTE: The cylinder head bolts should be examined BEFORE reuse. If the threads are necked down, the bolts should be replaced.

Necking can be checked by holding a scale or straight edge against the threads. If all the threads do not contact the scale (2), the bolt should be replaced.
